Using wolfSSL with #ContikiOS

Hi! Are you interested in using wolfSSL with the Contiki OS? If so, let us know at! The wolfSSL lightweight SSL/TLS library is a perfect match for resource-constrained embedded IoT devices. wolfSSL currently supports up to TLS 1.2 and DTLS 1.2, with TLS 1.3 support up and coming.

Contiki, as described by their website, is “an open source operating system for the Internet of Things. Contiki connects tiny low-cost, low-power microcontrollers to the Internet. Contiki is a powerful toolbox for building complex wireless systems.”

As those microcontrollers are connecting to the Internet, secure connectivity with SSL/TLS/DTLS is important. We look forward to hearing your thoughts about using wolfSSL with Contiki!

wolfSSL + Tenasys INTime RTOS

wolfSSL recently completed a port to Tenasys INTime RTOS! You can read more in the press release from Tenasys here: Secured INtime system traffic!

Tenasys is using wolfSSL to secure their networked real-time systems and wolfSSL is happy to be integrated into the INTime networking stack which allows us to provide world renowned security to INTime SDK consumers. If you have any questions about this please contact wolfSSL:


wolfSSL is Expanding Our Compatibility Layer

Tired of using OpenSSL? Recently wolfSSL has been expanding our compatibility layer, which means that it soon will be even easier to replace OpenSSL with wolfSSL in existing projects. In some cases the replacement can be as easy as including and linking to a wolfSSL library that has been compiled with –enable-opensslextra.

For more information about the wolfSSL or the compatibility layer contact us at

wolfSSL 2017 Roadmap

Curious about new features and additions to wolfSSL technologies for the coming year?  Some items on our current roadmap include increasing performance through hardware acceleration and instruction level tuning, resource reduction tuning, and increasing our Async Crypto support to other projects like nginx.  Our TLS 1.3 draft support is ready for testing and should the specification go final our release will be one of the first.

In terms of new environments we’ll have more FIPS platforms, more FIPS algorithms, easier integration with event programming, Data plane development support, more language wrappers, SGX support at the TLS level, and more Open Source project plugins including HAProxy, nginx, and wpa_supplicant.

Look for product improvements to wolfMQTT, wolfSSH, and wolfCrypt.  We also anticipate offering our testing and security audit programs as services.  Keep an eye out for connected home white papers and case studies.  Something we missed, or something you would like to see on our roadmap?  Please let us know.
